Boomextend is a mind game that resets ... your mind.
The principle is simple. Balls bounce on the screen. You have to detonate a number of them depending on the level.
If you play on a cell phone, don't be afraid by the yellow screen. Just swipe up the screen until you see the "new game" button.
Click the screen with the mouse, if using a computer, or with your finger on a mobile phone. You create an explosion.
Any ball that touches the explosion, in turn explodes and causes the explosion of any ball that touches it.
Simple and mesmerizing.
